| Abstract: | Pretreatment technology suitable for electroless Ni-P alloy plating on Al alloy was selected.A novel process of all bright electroless Ni-P alloy plating was established by adding Ni plating intermediate and inorganic salts into conventional electroless Ni-P plating bath.The effects of composition of the plating bath and plating conditions on the deposition rate,corrosion resistance and appearance of the coating were analyzed.It was found that the optimized plating bath consisted of 25~35 g/L nickel sulfate... |
